uplink_no_policy

 

Setting up NIC Policies: if uplink is down, veths can still be up based on the policy

But failover won’t work.

Available from 1.0.2d

 

 

 

 

 

 

Set this to all the service profile which u don’t want failover to work , but want the link to stay up when uplink fails.

 

 

Test

 

Linux Suse on Server 5 – eth0 – which corresponds vnic1 on Fabric B.

Redhat 5.4 on Server 3 eth0 – which corresponds to vnic1 on Fabric

 

 

 

 

 

 

 

 

Able ping router via uplink and ping the redhat linux (6120 switches within)

 

Let us bringdown the uplink

 

Able to ping the linux but not the router.

 

 

 

(I shutdown both uplinks still able to ping between the servers)
